The Property And Application of Boron Carbide Powder

Boron carbide

Also known as black diamond or organic matter, boron carbide is often gray-black micropowder with a molecular structure of B4C. Boron carbide is among the three most hard substances known.

Property of Boron Carbide

Boron carbide doesn’t react with acids and alkali solution. This is one the most stable acidic substances and it is stable in concentrated acid or alkali water solutions. Boron carbonide can be kept at a temperature of 800°C for a long time in an atmosphere.

While boron carbide has a lower hardness than the industrial diamond, it is more durable than silicon carbide. Boron carbide, when compared to most pottery is much less fragile. Boron carbide exhibits strong chemical resistance. It dissolves in molten alkali, but is not soluble in acid or water.

Boron Carbide

Control nuclear fission

Boron carbide absorbs a lot of neutrons but does not produce radioactive isotopes. This makes it an ideal neutron absorber in nuclear power stations. Also, the neutron absorber is responsible for controlling the rate at which nuclear fission takes place. Although it’s primarily made into a rod for control in the nuclear reactor fields, some people make it into powder because of its larger surface area.

Russia was responsible for nearly 2500 tons of boron and sand that it dropped during 1986’s Chernobyl nuclear incident. The drop eventually stopped the reactor from undergoing a chain reaction.

Abrasive material

For a long period, boron carbide was used as an abrasive medium. Due to its high melting points, it’s not possible for it to be used in artificial products. But, the powder can still be melted at high temperatures and processed into simpler shapes. This is useful for polishing and drilling hard materials, such as gemstones and cemented caride.

Coating paint

Boron carbide can be used to coat warships, and helicopters with ceramics. Boron carbide is very light and can resist armor-piercing bullets. It forms an integral defense coating.


This can be used in making gun nozzles within the munition industry. Boron carbide has an extremely high wear resistance and hardness.

Due to its wear resistance and hardness, the new boron caride sandblasting device will replace existing sandblasting devices such as cemented carbide/tungsten or silicon carbide, silica nitride, and zirconia.


Boron carbide may also be used for the production of metal borides.
